These ultra-flat glass substrates are coated with a 20 nm layer of synthetic quartz.
For many applications standard glass is simply not good enough due to either surface roughness or wettability. These synthetic quartz covered substrates are useful for a variety of activities such as absorption/PL measurements, OFET fabrication and surface profilometry where superior wettability and/or flatness are required.
Update: The substrates now come with small squares of ITO in the corners to help identify the SiO2 coated side.
